When trying to reassemble my slides, I run into the following error:

During handling of the above exception, another exception occurred:

I attach the slide's yaml file, and a screenshot.

What seems to be strange is the section

      text:
      - "Restklassen haben wir bereits kennengelernt. F\xFCr ein beliebiges \uFFFC\
        \ sind alle Zahlen, die sich um ein Vielfaches von m unterscheiden, \u201E\
        \xE4quivalent modulo \uFFFC\u201C.\nAnders gesagt: Die \xC4quivalenzklassen\
        \ werden dadurch gebildet, dass in einer (Rest)klasse alle Zahlen liegen,\
        \ die sich um ein Vielfaches von m unterscheiden.\nIn Zeichen: \uFFFC bezeichnet\
        \ alle Zahlen, die als Summe von \uFFFC und einem ganzzahligen Vielfachen\
        \ von \uFFFC entstehen \nEingesehen haben wir schon, dass bei den Restklassen\
        \ die Addition eine (kommutative) Gruppe bildet \u2013 die Multiplikation\
        \ ist assoziativ (und sogar kommutativ) und das Distributivgesetz gilt. Also\
        \ handelt es sich bei \uFFFC um einen Ring."

which starts with \xE4 in the third line. I suspect that this has been written incorrectly in the unpack phase.

This should now be fixed as of version 1.10.0.4 - please let me know if you still run into issues. And thanks for the bug report!

At least I could re-assemble the disassembled Keynote file. Unfortunately, it is smaller than before (missing about 1MB) and Keynote refuses to open it due to a "damaged file" error.

I'll see whether I can create a minimal example by bisecting the file… will take a few days, I fear. But thank you so much for your continuous efforts!
